The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for us over the next couple of weeks.

The honest truth is, the first week and a half is a bit of a dud. We’ve got a long stretch of small, weak swell and very ordinary conditions. The first real chance of anything worth paddling out for doesn’t show up until Tuesday, the 11th of August, and it’s only just surfable. Don’t get your hopes up too early.

Karramarro is a point break that really needs a good direction to light up, and it’s inconsistent. It’s also an advanced wave, so this isn’t a spot for beginners. The water is warm – 75°F, which is much warmer than normal for this time of year, so you can leave the thick wetsuit at home.

The first few days are a write-off. The 4th of August has a tiny 2ft from the WNW with a short 8-second period, and the wind is messy cross-on. The combined energy is only 45 – just a whisper. It stays like that right through the 5th, 6th, 7th, 8th, 9th, and 10th. We get some glassy mornings, like Friday the 7th and Sunday the 9th, but the swell is just too small, barely scraping 2ft. It’s a frustrating wait.

Finally, there’s a tiny flicker on Tuesday, 11th of August, in the morning. Swell is just 3ft from the NW, period 10 seconds, and it’s glassy. The energy is 190 – moderate. It’s surfable, but honestly, it’s still very ordinary. Not a standout.

The next real chance comes on Saturday, 15th of August, in the morning. Swell picks up to 4ft from the NNW, period 10 seconds, and it’s glassy again. The combined energy hits 244. It’s still only described as “surfable but very ordinary,” but it’s the best we’ve seen in a week. The afternoon sees the wind shift cross-on, so get on it early if you’re desperate.

But the real standout, the one that might actually be worth waiting for, is right at the end of the forecast. Wednesday, 19th of August, in the morning. This is still a long way off, so treat it with a bit of caution, but the numbers look tasty. We’ve got a solid 13ft from the NW, with a 10-second period. The combined energy is a massive 2948. That’s serious. The wind is light and cross-shore, so it’ll be a bit bumpy, but with that much swell, it’ll be on. The afternoon is similar, with cross-on wind, but still 13ft and 3063 energy. This is a big, powerful swell – it’s going to be for experienced surfers only. The point should handle the size well, but the inconsistent nature of the break means you’ll have to be patient for the sets. The wind won’t be perfect, but the power is undeniable.

So, to wrap it up: the first ten days are a struggle. The standouts are the glassy morning on Saturday the 15th for a small, clean wave, and the big groundswell potential on Wednesday the 19th of August for the advanced crew. That big swell is the one to circle on your calendar.

Rusty.

Information about the Karramarro Surf forecast

The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
